One more thing about naming indexes conventions. Indexes namespace is
global. So if you have several same fields in different tables, you'll have
the same name index for both. Good example in three entities with N:M
relations:
Entity1: eid, name
Entity2: eid, name
Entity3: eid, name
That’s not the same as what AddInterceptor call does.

As far as I see in the debugger, MigrationsTransactionsInterceptor is
called successfully and failed tests are going further. I've added just one
fix to filter just Firebird connections:

Yeah, but it’s different path. The InternalConfiguration class might or might
not like that (now or in the future). It’s problem waiting to happen.

According to this:

As I understand DbConfiguration.AddInterceptor is for context instance
interceptions.
And DbInterceptors.AddInterceptor is for global-wide interceptions.

Ahh. Finally found it. IdbInterceptors are not supported for registration in
DbProviderServices. So we're probably left with only DbInterception.Add. I did
some research and looks it should work

I've asked about mutual exclusive of schemes.
If schemes can be applied in one model you can use custom attributes on
primary keys.
If schemes are mutual exclusive, you can use custom extension method for
model builder.

It kind of breaks the notion of altering the table/column with one command.
It's a bit of magic with system tables and people might get confused or break
